  1. Ultra-processed (NOVA 4): Classified NOVA 4: made with industrial ingredients and additives. Strong
  2. Acesulfame potassium (Ace-K): In the NutriNet-Santé cohort, acesulfame-K intake was associated with higher cancer risk; cause and effect is not established. Strong
  3. Sucralose: In a 2022 randomized study, sucralose and saccharin altered the gut microbiome and impaired glucose responses in some people; a 2023 lab study raised questions about its by-product sucralose-6-acetate. Strong

Every line of the math is on The Receipt below, with its evidence tier and sources.
